Hi there,
Totally understand why that felt confusing!
The way it works is that we have a dedicated pool of free Gems to give away each period. Thanks to the Gem Boost, we are now able to spread that pool across many more winners than before so more Ribblrs can land on free gems and get something - and it does add up!
The amount itself is random, so sometimes it may be a small win and sometimes it may be a much bigger one. The main idea is to spread the pool across more winners overall.
That said, I do hear you that a small amount can feel low. I’ve already passed it along to our team and I appreciate you sharing your thoughts!
